Thanks for advice, but just thought that I can get some quick reply, as hacker community is available here. Even if somebody would have suggested name of software to wrap jar file for Linux, that would have been enough, because I couldn't find it in Google search. Anyways if nobody answers I will of course ask same question on other programming forums.
Great thing. It reminded me of the time when I used heuristics for developing tic-tac-toe in C. And realized that to make computer play a simple logical game it takes hundreds of lines of code. So I really appreciate the amount of thinking gone in developing such AI entirely from discrete states of HTML pages.
